Giant cell tumour of hyoid bone: case report

Giant cell tumours of bones are uncommon and are usually found in the epiphyses of long bones. They are rare in flat bones (<10%). The tumour has to our knowledge never been described in the hyoid bone, although 18 cases have been reported in the cartilagenous laryngeal skeleton. We report a giant cell tumour of the hyoid bone in a 45-year-old man, which we excised along with the left half of the hyoid bone. It recurred locally one year later and was cured by excision and split course radiotherapy. The patient is disease-free after 30 months of follow-up.
